To all whom, it mar concern:

Be it known thatI, JAMES W. TAYLOR, a citizen of the UnitedStates,'residing at Goldsboro, in the county of Wayne and State of NorthCarolina, have made certain new and useful Improvements in Machines forApplying Gathering-Strings to Bags, of which the followingis aspecification. Bags for holding various substances, especiallysmoking-tobacco, are commonly provided with gathering orshirringstringsfor closing their mouths. Two such strings are inserted in the oppositehems or folds formed at the mouth of the bags, and their free orlooseends are knotted to prevent accidental detachk ment of the strings. Bypulling such knotted ends the mouth of abag is puckered or drawn of thecontents under-"ordinary conditions. Such strings have usually beeninserted by.

ployed with some measure of success.

It is the object of my invention to entirely dispense with hand laborfor this purpose and to provide an improved automatic macheaper, anduniform manner.

The machine includes many novel features of construction, arrangement,and operation of parts, as hereinafter set forth, and illustrated in theaccompanying drawings, in which 1 i Figure 1 is a plan view of a mainportion of the machine. Fig.2, Sheet 2, is a side eleva- 4, Sheet 4, isin part a side elevation and in ticularlyillustrating the mechanism forplacing the bags upon the pins which hold them during the subsequentoperation of stringing. Fig. 5 includes-a side view and an edge view. ofone of the sprocket-wheels upon which the endless bag-carri'erissupported and travels. Fig. 6 is a side viewof an escapement and lockingmechanism for the endless carrier. Fig. 7, Sheet 5, is a verticalenlarged crossomitted. Fig.8, Sheet 6, is a vertical enlarged section ofa portion of the machine,

Fig. 9, Sheet 7, is another enlarged vertical transverse section,further illustrating the bag-stringing mechanism and means for.operating it. Fig. 10 is a perspective view of the needles and theslidable bar employed for locking the endless traveling carrierintermittently. Fig. 11 is a reduced end view of the parts shown inFig.10 and including the fixed bracket in whichthe locking-bar slides.

Fig. 12 is a vertical cross sectiowof the part shown in Fig. 11. Fig.'13 includes a top view and a face view of a guide-plate for the slidingblock carrying the pointed pins by which the hems of the bag aredistended to receive the stringing-needles. Fig. 14., Sheet 8, is aperspective viewillustrating the mechanismjfor drawing ofi a bag-stringfrom a suitable source of supply and severing the same to thread a bag.Fig. 15 includes detail views of one of the spring-clamps andthejcutters for holding and severing the bagstring. Fig. 16 is a detailvertical section on the lines 16 16 of Fig. 17, illustrating the partsemployed for distending the hems of a bag. Fig. 17 is a face view, partbeing in section, of the parts shown in Fig- 16. Fig. 18 is a plan viewof the parts shown in Fig. 16. Fig. 19 is a view similar to Fig. 17 savethat it illustrates the operation of the parts. Fig. 20, Sheet 9, isasectional detail view showing a bag in the position itusually assumeswhen first applied to the pinswhich support and distend it. Fig. 21 is asimilar view illustrating the operation by which the hems of the bag aresupported horizontally in the same plane preparatory to entrance of thepins for distending said hems. Fig. 22

is a perspective viewillustrating the distention of the bag-hemspreparatory to entrance of the stringing-needles. Fig. 23 is a partlysectional 'view of the enlargedpoint of one of the bag-stringingneedles. Fig. 24 is a similar view illustrating the passage of a stringinto the eye of a needle. Fig. 25 is a 5 perspective view showing theneedles insert- 1 ed through the hems of abag and applying one of thestringsthereto. Fig. 26 is anparticularly illustrating the arrangementof 50 which support them and stretch their mouths during the subsequentoperations; second, drawing off string from a spool or other source ofsupply and severing a portion or length thereof suitable for one of thestrings proper; third, threading or stringing the needles; fourth,inserting the strings in the heme of the bags; fifth, releasing tensionon the mouths of the bags and allowing the latter to discharge from themachine.

The frame A A of the machine is made duplex or double (see Fig. 3) inorder to support two complete bag-stringing mechanisms, which areoperated from a single drive-shaft 13, arranged intermediately of thetwo duplex portions of the frame. The following description will relatechiefly to one of the two duplicate mechanisms, and a description of thesame will answer in general for the other.

As shown in Fig. 4, the bags as received from a sewing-machine (notshown) aredelivered to this machine by means of parallel rollers 1.

andby means ofasWingingclampOare seized, raised to avertical position,and then dropped upon the holding and stretching pins 13 13. Suchswinging clamp consists of a fixed bar 2 and a movable bar 3, a fixedcam 4, and means for swinging the clam p, as will be presentlydescribed. The main portion of the clamp consists of a bar 2, whoselower end is bent laterally, and the sliding bar 3 has a similar bentportion,thereby forming opposite jaws, which are provided with rubberpads on their inner sides to adapt them to seize and hold a bag m. Thebar 2 is provided with a slot 5, through which projects a stud 6 fromthe sliding bar3. A spring 7is applied to the stud Sand connected with asimilar stud on the bar 2 forthe purpose of holding the slidable bar 3in such position that its jaw is normally separated from the fixed bar2. The bar 2 is keyed upon a shaft provided with a pinion 8, and whensaid shaft is rotated the clamp begins to move to the right, as in Fig.4, whereby the upper end of the slidable rod, comes in contact with thefixed bar 4, and the jaws are thereby closed upon the bag. The swingingmovement being continued until the bag-clamp reaches the position shownby dotted lines in Fig. 4, the slidable bar slips off the cam 4, andthejaws being thereby opened the bag is released and falls upon theguide and stretching pins 13 13 The means for operating the swingingbag-clamp O is a rackbar 9, arranged vertically in suitable guides andconnected with a pitman 10, which is operated to reciprocate therack-bar 9 vertically by means of cam 11, fixed on the rotary shaft 12.The'latter is suitably geared with the driving-shaft B. It is apparentthat the bagcla'mp is operated-thatis, caused to seize a bag and swingto a horizontal position and then return to place-at each revolution ofthe cam 11, the clamping action and the releaseof the bag being in bothcases automatically performed.

Each pair of pins 13 l3 is attached to and carried by an endlesstraveling belt D, which is formed of a series of rigid metal plates 14,connected by joints or hinges 15. (See Figs. 3 and 7.) This endlesscarrier D is supported by flanged wheels 16, which run in slottedguideways 17 in the upper portion of the frame A, and on rails 17,arranged horizontally in the lower portion of the frame. (See Fig. 2.)The wheels 16 are mounted upon axles 16. (See Figs. 7 and 8.) Stub-axlesmight, however, be employed with equal facility. The axles pass throughalined lugs formed at the adjacent ends of carrier plates or see--tions'14. At the ends of the machine-that is to say, of the frame A-theendless carrier D passes around and is duly supported by two verticalsprocket-wheels 18, which are shown in detail in Fig. 5. The said wheelsare hexagonal and provided at the apexes of their angles with sockets orsemicircular grooves 19 for receiving the axles of the wheels 16. Eachpair of sprocket-wheels 18 is supported by a shaft 20, arrangedtransversely in suitable bearings provided with brackets 21, attached tothe end portions of the frame proper, A. One of the pins 13 is fixed inplates or sections 14, comprising the body of the endless carrier, andthe other pin 13 is movable laterally with relation to the first for thepurpose of duly stretching a bag after being placed thereon. For thispurpose eachmovable pin 13 is fixed in a block 21, adapted to slide inone of the dovetail grooves 22, formed in each ofthe plates or sectionsof the endless carrierD. \Vhen the bags have been dropped upon a pair ofpins 13 13 at the left-hand end of the machine, the endless carrier D ismoved, whereby the pin 13 ismoved laterally and distended sufiicientlyto stretch the mouth of'the bag to the required degree. This movement iseffected chiefly by a fixed cam 23, (see dotted lines, Fig. 1, and fulllines, Fig. 7,) which acts upon an antifriction-roller 24, mounted upona stud 25, pendent from the sliding block 21. Said stud projects downthrough the lengthwise slot 26, formed in each carrier plate or section14. The cam 23 is supported in horizontal position by means of rods orpins 27, (see Fig- 7,) that work in guides 28, projecting from a sidebar of the frame A. Spiral springs 20 are arranged behind the pins 27 insockets in the bars 28 and serve to force the cam 23 outward to therequired degree. The ends of the cam 23 are suitably curved, as shown inFig. l, to adapt the wheels 24 to pass easily into and out of engagementwith it. In some cases the bags may differ in size, and to provide forthis a series of holes may be formed in the sliding block 21 to receivethe pin 13 bags I provide a spring-cam 30, (see dotted lines, Fig. 1,)which is a bar curved reversely and attached to the side of the frame Aand suitably arranged horizontally beneath the top portion of theendless carrier D, so as to strike upon the wheel 24, attached to theslide 21, and thereby force the latter later ally in its groove to thepositionrequired for the pins to receive another bag when carried aroundto the opposite end of the machine.

The means for drawing off thread froma spool or other suitablesource ofsupply and severing a portion of such length thereof as is required toform a bag-string are as follows:

Referring especially to Figs. 1 and 14, 31 and 32indicate twospring-clamps which are fixed vertically upon a bracket onthe side ofthe frame A and alined. in a plane parallel thereto. These clampsareformed of platesprings, which are bent outward or flared at their upperends. The clamp 32 is shown in detail in Fig. 15 and provided with twocut ters 33, which are attached opposite each other near the upper endsof the clamp, as shown. These cutters 33 are enlarged at their bases, sothat their edges cross,and are thereby adapted to make shear cut. Eachof the jaws of theclamp is provided with a rubber block or facing 34. Athird or swinging clamp 35 is arranged to move vertically in the are ofa circle and to pass downbetweenthe fixed clamps 3132. If now it besupposed that a string 3 from a spool or other sourceof sup ply has beenalready drawn between the fixed clamps 31 32 and is held by frictionwith the rubber blocks 34, it will be'apparent that when the clamp 35 isswungover, as shown by dotted lines, Fig. 2, its jaws will pass over andseize the string thus held stretched between the clamps 3132. It isfurtherapparw cut that if at this moment the clamps3l 32' be released oropened the swinging clamp 35 may take the string Withitand, swingingback to the horizontal position shown in Fig. 14, will draw the stringoff from the spool and also down between the jaws of the clamps 31 32,as indicated by the dotted lines. In this position the string is inreadiness to be operated upon and pulled down into-the eyes of theneedles, as will bepresently described.

The means for opening or releasing the clamps 31 32, as above stated,are as follows: The conical pin 36 (seeFig. 13) is arranged between eachof the spring-jaws and its pointed end engages theirinwardly-inclinedportions. It now this pin 36 be forced ,up-

ward, it is. apparent the jaws will be opened. Such movement is effectedby tappets 37, which are fixed on and project horizontally to releasethe string.

from a rock-shaft 38, held in suitable bearings at the side of themachine. These tap.- pets "37 project beneath the reduced shanks 36 0fthe conical pins 36, which work in-suitable guides at the base of theclamps 31 32. It is apparent that if the shaft 38 be rocked the tappets37 will force the pins 36 upward, and thereby release the pins. Theswinging string-clamp 35 is opened by reason of its pin 36 striking upona lateral shelf or bracket 39, attached to thesideof the machine.

Toadapt the needles 40, which are arranged parallehas shown, toreceivethe string y, they must be retracted in the position shown inFigs. 1, 8, and 9. As shown in Figs. 23 and 24, the needles areprovidedwith an eye41, which is open at one side and provided with alatch 42, supported by a string 43. It is ap parent that if thestring ybe pressed down- ;cate vertically between the two needles, as shown.length of string y, as before described, the string strikes upon'theinclinedor beveled gportion of the hook 44 and slides over the nose ofthe same into position beneath the latter and between itand the needles.If now the hookdescen ds, it will exert traction upon the string y, andthe clamps31, 32, and 35 not bein g yet released the string will havesufficient :tension to enable the hook to draw it into the In theoperation of drawing off a eyes of the needles. The instant this isdone, however,the clamps 31, 32, and 35 arejopened readiness to advanceto carry the strings through the hems of the bag. The hook'44 is raised(see Figs. 8 and 14) by means of a cam 45, mounted upon a shaft 46 andact-ingupon an antifriction-roller 47, mounted upon a stubjournal 48,projecting fronrthe inner side of the hook 44. The lower portion of thehook 44-to wit, its shank-is broadened and en larged and provided with alengthwise slot and adapted to embrace reduced portion of the shaft 46.A collar 48 .isappliedto the outer end of said shaft to serve as a guidefor the hook in its vertical movement, .While the book 44 is raised bymeans of the cam 45,

as ab0vestated,it isretracted. by a spiral spring 49, which encircles apin 50 that works in a. yoke or cross-bar at the lower end of the 11001;44. s The upper end of thespring 49 acts against a block 51, which iscut outon its upperside to adapt it to work in contactwith theshaft 46.Thehook: 44 is provided with a laterally proj ectin g pin 5.2,whichpasses under the free outer end of a lever arm and the latter is fixedupon the rock-shaft 33, which operates the tappets37. It isthus apparentthat the book 44 performsitwo functionsin that as it rises it acts uponthe lever-arm 53 to rock thejshaft38 and cause re- The needles are nowinjward upon the latch 42 it will pass into the eye, as indicated, inFig.24. This engagement is effected chiefly by means of the hook 44,(see Fig. 14,) which is adapted to recipro- ICC lease ofthestring-clamps3132,and,sec-

ondly, in its reverse or downward movement bracket 69. the pendent arm68 with an obtuse-angled lever 71, which is pivoted (see also Fig. 2) onthe hook strings the needles, as before described. The means foroperating-that is, swingingthe string-clamp 35 arethe following:

cent to the cam 45, which operates the hook 44. It will be seen thatupon rotation of the shaft 46 the elbow-lever 59 will be oscillated andthe rack-bar 57 thereby caused to rotate the pinion 56 and throw theswinging clamp 35 over into the position shown by dotted lines, Fig. 2,and that the reverse movement The shaft' will be effected by a spring63*. 46 derives rotation from one' of the shafts carrying thesprocket-wheels 18, as shown in Figs. 1 and 2, through the medium ofsprocketwheels 138and sprocket-chain 139.

As shown in Fig; 10, the two needles are fixed in a suitable head orcross-bar 66, to which a bar 67 is also secured. This bar 67 serves asone of the means for locking the bag-carrier D,as will be hereinafterdescribed. An arm 68 (see Figs. 8 and 9) is pendent from thislocking-bar 67, which slides in'a dovetail groove in a lateral bracketor arm 69, projecting from the machine, as indicated in Fig. 1. The arm68 projects down through and moves in a lengthwise slot formed in thelateral A link or pitman 70 connects a rod 72 at the lower portion ofthe frame A and is provided with a wrist-pin 73, working in the grooveof a cam 74, which is keyed upon the shaft 75 and derives motion fromthe drive-shaft B through the medium of a gear 76, that meshes with asmaller gear 77, mounted upon said drive-shaft. I By'the revolution ofthe cam 74 the lever 71 is oscillated to cause retraction and dwell ofthe lockingbar 76 and the needles 40, as required. Preparatory topassage of the needles 40 with strings applied thereto, as alreadydescribed,

. through the hems of the bags at it is necessary that the said hems bein due position and that they also be distended. It is found in practicethat most of the bags are of unequal length on the opposite sides-thatis to say,

that the hems formed at the mouth on the opposite sides are notexactly-even'or not the same distance from the bottom of the bag, asillustrated in Fig. 20. It is necessary that the hems shall be in thesame horizontal plane prior to the introduction of the needles. This iseifected by pressure from below, which is applied to that hem whichprojects lowest by means of a vertically slidable block 78. (See Fig.21.) This block is adapted to slide vertically in a dovetail grooveformed in a plate or block 79, (see Fig. 13,) fixed on the side of theframe A. As shown in Fig. 8, the block 78 projects upward through a slotin a section or plate 14 of the carrier D and is raised by means of acam 80, fixed on the rotary shaft 46, and acts upon anantifriction-roller 81, attached to the lower end of said block. Thiscam 80 thus serves to raise the block 78 each time that a bag comes intoposition to be threaded, and the hem that projects lowest will bethereby raised and flattened, as shown in Fig. 21. In addition to thusevening the mouth of the bag it is requisite to distend the mouths ofthe hems at the ends of theneedles 40. This operation is effected bymeans of separable points 82 83, constructed in a peculiar manner. Thepoints 82, which are shortest, are fixed in positionin the block 78, butthe points 83 are movable laterally or outward from the points 82inorder to distend the hem, as shown in Fig. 22. As shown in Fig. 21, thetwo pins of each pair are so beveled as to form a common conical pointadapted to enter a hem of the bag, and when the block 78 is forcedupward, as before described, the two pairs of conical points enter thehems as shown in Fig. 1. The next step is the lateral movement of thepoints 83, which distends the hems. In Fig. 17 the two pairs of points82 83 are shown together, as when they enter the hems of the bags. InFigs. 18 and 19 they are shown separated as required to distend the hemsof the bags, as shown in Fig. 2. To elfect this, the points 83 are fixedto laterally-slidable blocks 84. The latter are arranged in a horizontaldovetail groove formed in the vertically-slidable block 78, and theirinner adjacent ends are beveled at the lower edge to provide forentranceof a wedge 85-between them. The

said wedge is adapted'to slide vertically in a groove in the centralportion of the block 78 and provided at its lower end with anantifriction-roller 86, which works in contact with a cam 87, fixed onthe rotary shaft 47. (See Fig. 8.) The slidable blocks 84 are heldnormally retracted or drawn together by means of a spiral spring 88(shown in dotted lines, Figs. 17, 18, and 19) and arranged in suitablecavities in the block 78. To recapitulate, the cam 80 raises the block78, and thereby the points 82 83 are forced upward into the hems of abag, whereupon the cam 87 comes into action and forces the wedge 85between the sliding blocks 84 and forces them asundera distancesutficient for the proper distention of the baghems. The needles 40 thenadvance and enter the hems, and in the remainder of their passagethrough the latter they are suitably guided and pass out at the otherend of the hems, thus carrying one of the puckeringstrings y entirelythrough the hems, as illustrated in Figs. 25 and 27. When the needlespass the due distance beyond the bag on the opposite side from theirpoints of entrance, they receive another string, which is applied.capement 130 is movable or unlocked.

by mechanism similar to that already described, and therefore requiresno specific description nor full illustration. Said mechanism is,however, illustrated in part in Figs. 7 and 9. The needles 40 are thenretracted, and thus carry a second string y through the hems of the bagand leave the free ends of the same projectingonthe sidefrom which theneedles first enteredthat is, a bag is provided with two strings whoseends project on opposite sides. The next step in the operation isknotting the ends of the stringy thus applied to the bag.

I will now describe the means for moving and locking the endless carrierD. 1

The locking-bar 67 (see Fig. 9) has been before referred to. It isconical orwedge-shaped at its outer end and. is adapted to slide intoone of the dovetail grooves 128. (See Figs. 1 and 4.) One of suchgrooves comes directly opposite the locking-bar 67 when a pair ofbag-holding pins 13 13 are in proper horizontal alinement with theneedles 40. i This position is shown in Fig. 1, in which the dottedlines also indicate the extent to which the bar 67 projects from theopposite side of the carrierD when forced inward for locking the latter.As shown inFigs. l1 and 12, the lockingbar '67 is guided laterally inthe dovetail. groove in bracket 69, (see also Figs. 8 and,9,) affixed tothe side of the machine. A further means for locking the carrier D iscombined with the means for intermittently moving it. The said meansconsist ofan escapement- Wheel 130 (see Fig. 6) and crank-arm l3land amultilated or cut-outdisk 132. The escapement 130 is a plate having aseries of open slots 133 in its periphery and a series of interveningarcs 134. The crank arm 131is keyed upon a transverse shaft 135,which isarranged in suitable hearings in the two framesA and A. (See Fig. 3.)The crank-arm carries an antifriction-roller. on its wrist-pin, which isadapted to work in the radial slots 133 of the escapement 130. The shaft135 is constantly rotated, and it will be seen that the escapement 130must therefore receive an intermittent rotary motion. Theescapement iskeyed upon one of the shafts-20, (see Fig. 3,) carrying thesprocket-wheels 18, upon which the two endless carriers D are supportedandrotated at one end of the frame. The disk 135 is adapted to fit andwork in the arcs 131 of the escapement 130,so that while the wrist-pinof the crank is free from the radial slots 133 the es- Thus theescapement serves for moving the carriers D the required distanceintermittently and is locked by the disk 132 during the time that a bagis being applied to the pins 13 13 and another bag is being duly strungand the strings of another are being knotted. In other words, theseveral operations of placing the several ,bags upon the pins, ofdrawing 0% stringsfrom a spool or other source of supply, the stringingof the bags, and thetying of the knots are all performed practicallysimultaneously, and then the endless carrier D is moved a distancerequired to advance the bags one step-that is, the distance between theapexes 19 of the sprocket-wheels 18,(see Fig. 5) or the width of one ofthe .the recess or cutout port-ion of the disk.132,
